Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42338, here are decompositions:

7 + 42331 = 42338
31 + 42307 = 42338
151 + 42187 = 42338
157 + 42181 = 42338
181 + 42157 = 42338
199 + 42139 = 42338
277 + 42061 = 42338
379 + 41959 = 42338

Showing the first eight; more decompositions exist.
